Abstract
Rhythmological features of 11 species of the genus Campanula L. of different ecologo-geographical origin have been studied. It is revealed that the natural and climatic conditions of the forest-steppe of Western Siberia represent the zone of ecological optimum for the growth of these mesophilous species, which is appeared as stable, well adapted rhythms of seasonal development. Their phenorhythmotypes are long-growing with early or medium terms of regrowth, spring-summer or summer-flowering, inherent to the herbaceous polycarpics of aboriginal flora. The high phenodates variability is established, while the duration of the main periods of seasonal development varies less, confi rming the stable character of the rhythmological processes in the species under introduction.
